Q: the heater is not working right on 2007 Pontiac Grand Prix

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
i noticed about a week ago that my car did not feel as warm as it use to. there was not enough heat coming out of the vent to keep me warm. but enough heat was coming out to melt the snow off the windshield. i am not sure whats going on with the heat in my car.

Check the coolant level in the radiator/expansion tank if it is low air can get in the heater core. Another likely cause is a failed cooling system thermostat, if it is stuck open or partially open the heater will not be operating efficiently.
